Roblox Launches Build: A Mobile Tab That Turns Text Prompts Into Playable Games

Roblox launched Build, a mobile-first AI creation tab that generates games from text prompts, starting alpha testing in New Zealand on July 28.

Key Features:

  • AI-Powered Game Generation: Build uses AI to create basic playable games based on text descriptions.

  • Agentic Playtesting: A playtesting agent identifies and fixes bugs before players encounter them.

  • Shared Backend: Creators can start projects on mobile and continue refining them on desktop, or launch agents from Studio to monitor progress from their phone.

  • Retention-Based Discovery: Games are ranked based on long-term player retention, ensuring only quality games appear on the Roblox homepage.

  • Targeted Safety Checks: Games for younger players undergo extended review before being added to appropriate catalogues.

Build is part of a broader push by Roblox to integrate AI into its platform, including agentic tools for professional creators and a scene generation model that creates entire 3D environments from text prompts.

This launch comes as AI-generated content inundates platforms, leading to concerns about quality control. Roblox believes its retention-based discovery system will act as a natural filter, promoting only games players want to play.
